IT之家 8 月 22 日消息，由北京市人民政府、中央广播电视总台等单位联合主办的第二届世界人形机器人运动会今天开幕。本次比赛将持续到 26 日，共设置 51 个项目、1300 多场比赛。今年竞技赛新增跳远、举重、拔河、乒乓球等高强度对抗项目。本届运动会正赛将于 8 月 22 日至 26 日在国家速滑馆“冰丝带”举行，将举行 51 个项目共 1301 场比赛，吸引 666 支队伍携 2056 台机器人参赛，竞赛项目、参赛队伍全面提质扩容。从报名情况来看，各路高手将云集赛场。本届赛事吸引了来自六大洲、16 个国家的 666 支队伍，共有 2056 台机器人同台竞技，队伍数量较首届增长 138%，机器人数量翻了两番。

二 | 国际方面，美国、德国、日本等机器人传统强国赛队积极参与，巴西还集结了五支机器人足球世界杯队伍，组建起一支国家联队参赛。国内方面，157 家企业、200 所院校和科研机构的 641 支队伍、1975 台机器人齐聚赛场。国内第一梯队企业悉数到场，27 所 985 高校踊跃参赛，产学研用各方力量汇聚一堂。    STOCKHOLM -- A ban on gasoline and diesel-fueled cars from a commercial district of Stockholm's downtown in 2025 will be the first for a European capital, a city official said Thursday.The ban will take effect in a 20-block area of shops, pedestrian walkways and a few homes in order to curb pollution, reduce noise and encourage use of electric vehicles said Lars Strömgren, the city council member for the Greens who's in charge of the Swedish capital's transportation. Many European capitals have restrictions on gasoline and diesel cars, but Strömgren says Stockholm’s complete ban would be a first. “We need to eliminate the harmful exhaust gases from (gasoline) and diesel cars. That’s why we are introducing the most ambitious low-emission zone to date,” Strömgren told The Associated Press. The idea is to create an "environmental zone” where only electric vehicles will be allowed. There will be some exceptions such as for emergency vehicles and transportation for the disabled.In its budget for 2024, the left-leaning, environmentally-focused city council on Tuesday unveiled the plan for the target area just north of the city’s famed Old Town. The municipal government controls a majority in the council, so the vote set for Nov. 23 is expected to be a formality. “We are pretty proud, I must say,” Strömgren said, adding that gradual expansion of the environmental zone would be decided in the first half of 2025.One of the city’s main cab companies, Taxi Stockholm, said its transition to emission-free vehicles is moving at a fast pace. The company’s acting chief executive Pernilla Samuelsson said it's emission-free vehicles now make up 30% of its fleet - almost seven times more than last year. “In other words, the transition is going fast and it is already being driven forward by the industry,” Samuelson said.Some aren't convinced things will go smoothly. Nike Örbrink from the opposition Christian Democrats told the Aftonbladet newspaper that some are concerned the plan would hurt businesses and the hotel industry.Other European capitals harbor similar ambitions. The Dutch capital, Amsterdam, is aiming for all transport in the city, including automobiles, to be emissions-free by 2030.The mayor of Paris wanted to ban all diesel cars before next year’s Olympics, and gasoline cars by 2030, but has run up against resistance.Currently, any diesel cars built before 2006 and gasoline cars built before 1997 are banned in Paris and 77 surrounding towns for 12 hours a day on weekdays. The ban will expand in 2025 for diesel cars built before 2011 and pre-2006 gasoline vehicles.___Jan Olsen reported from Copenhagen, Denmark.

三 | 在竞技赛中，今年新增的跳远、举重、拔河、乒乓球等高强度对抗项目，都是对机器人大脑、小脑、本体结构以及核心零部件的极限考验。赛场上每多跳远 1 厘米、每多举起 1 公斤，都是工程师们对关节电机、减速器不断优化设计、精密加工、测试验证的结果。此外，田径场比拼将更加激烈，机器人足球比赛将实现带球跑动、大力抽射等技能提升，更有百支队伍上演“舞林争霸”。本届场景赛则将赛项延伸到真实环境，覆盖工业、酒店、家庭、物流等领域，并专门设置了灵巧手赛项。其中，灵巧手设有夹豆子、拧螺丝等 8 个“微操”赛项，上演指尖对决。相比去年场景赛机器人仅“一个人战斗”，本届升级为机器人两两同台比拼，进一步增加赛事的精彩程度和观赏性。
